What role does evolution play in the emergence of antibiotic resistance in bacteria?

tiny-mole [99]

1.Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

2. Bacteria evolve quickly because they grow fast and can share genes. Helpful mutations spread quickly in bacteria.

3.Taking antibiotics too often or for the wrong reasons can change bacteria so much that antibiotics don't work against them. This is called bacterial resistance or antibiotic resistance

4. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality. The world urgently needs to change the way it prescribes and uses antibiotics.

Which of the following exposure factors will produce the greatest receptor exposure?

earnstyle [38]

400 mA, 70 ms is the following exposure factors will produce the greatest receptor exposure.

C: 400 mA, 70 ms

Explanation:

As SID builds, the introduction rate diminishes and receptor presentation diminishes. SID and the mAs required to keep up the introduction to the IR have a straightforwardly corresponding relationship (as the SID builds, the mAs required to keep up presentation to the IR increments by a corresponding sum).

An expanded SID likewise decreases amplification (size twisting). The most extreme SID ought to be utilized when conceivable to limit amplification. Infrequently, however, the SID can be purposefully diminished for amplification. SID influences size yet not shape twisting.

The most common form of hemophilia is a defect in blood clotting factor VIII, which is caused by a mutant form of a gene on the

natta225 [31]

Answer:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.

Explanation:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.

It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.

However, such mutant (X) communicates and expresses itself and she is hemophilic.

This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.
